    34d + 27s = 780

    d + s = 25

    d + s = 25

    s = 25 - d

    34d + 27 * (25 - d) = 780

    34d + 675 - 27d = 780

    7d = 105

    d = 15

    15 doubles, 10 singles

    34 * 15 = 510

    10 * 27 = 270

    510 + 270 = 780

    27S+34(25-S) = 780

    -7S = -70

    S = 10 Single Rooms

    and 15 Double Rooms
